Description

Die vorliegende Erfindung betrifft eine Abgabevorrichtung gemäß den Merkmalen des Oberbegriffs des Anspruchs 1. Eine Abgabevorrichtung, die diese Merkmale zeigt, ist aus EP 442858 bekannt.The present invention relates to a dispenser according to the features of the preamble of claim 1. A dispenser showing these features is made EP 442858 known.

Unter dem Begriff "Abgabevorrichtung" ist bei der vorliegenden Erfindung insbesondere eine Dosierpumpe bzw. handbetätigte Pumpe zur Abgabe einer vorzugsweise kosmetischen Flüssigkeit zu verstehen. Jedoch kann es sich auch um jede sonstige Abgabevorrichtung, wie einen Behälter, Ausgabe- oder Sprühkopf, Spender oder dergleichen, insbesondere für eine kosmetische Flüssigkeit, handeln.The term "dispensing device" in the present invention is to be understood in particular as meaning a metering pump or hand-operated pump for dispensing a preferably cosmetic fluid. However, it can also be any other dispensing device, such as a container, dispensing or spraying head, dispenser or the like, in particular for a cosmetic liquid act.

Unter dem Begriff "kosmetische Flüssigkeit" sind in einem engeren Sinn Körperpflege- und -Reinigungsprodukte, Kosmetika oder dergleichen zu verstehen. Grundsätzlich kann es sich um eine Lotion, ein Gel, eine Suspension oder sonstige Flüssigkeit, gegebenenfalls aber auch um ein Fluid mit einer Gasphase oder dergleichen handeln. Es kommen auch technische Flüssigkeiten und Fluide in Betracht. Nachfolgend wird jedoch aus Vereinfachungsgründen und aufgrund des Nutzungsschwerpunkts oft nur von kosmetischer Flüssigkeit gesprochen.The term "cosmetic liquid" in a narrower sense means personal care and cleaning products, cosmetics or the like. In principle, it may be a lotion, a gel, a suspension or other liquid, but if appropriate also a fluid with a gas phase or the like. There are also technical fluids and fluids into consideration. However, for reasons of simplification and because of the focus of use, only cosmetic liquid is often referred to below.

Die EP 0 442 858 A2 offenbart eine Abgabevorrichtung mit einem Unterteil und einem elastischen Oberteil. Zwischen dem Oberteil und dem Unterteil ist eine Pumpkammer gebildet. Durch Niederdrücken des Oberteils oder zumindest eines Betätigungsabschnitts des Oberteils ist eine Flüssigkeit aus der Pumpkammer verdrängbar und abgebbar. Anschließend erfolgt ein selbsttätiges elastisches Rückstellen des Oberteils bzw. Betätigungsabschnitts, wobei neue Flüssigkeit in die Pumpkammer gesaugt wird. Es ist schwierig, ein geeignetes Material für das Oberteil zu finden, um die gewünschten Eigenschaften - insbesondere hohe chemische Beständigkeit und hohe Rückstellkräfte - zu erreichen.The EP 0 442 858 A2 discloses a dispenser having a base and an elastic top. Between the upper part and the lower part of a pumping chamber is formed. By depressing the upper part or at least one operating portion of the upper part, a liquid can be displaced from the pumping chamber and released. Subsequently, an automatic elastic resetting of the upper part or actuating portion, wherein new liquid is sucked into the pumping chamber. It is difficult to find a suitable material for the upper part in order to achieve the desired properties - in particular high chemical resistance and high restoring forces.

Die DE 1 934 235 U offenbart eine ähnliche Abgabevorrichtung, wobei ein elastisch verformbares Oberteil etwa halbkugelig ausgebildet ist und zur Erhöhung der Rückstellkraft außenseitig radiale Versteifungsrippen aufweist, die in einem ringförmigen Wulst am Kopf des Oberteils enden. Der ringförmige Wulst dient zugleich zur Führung eines Fingers beim Niederdrücken des Oberteils. Auch hier ist die richtige Materialwahl für das Oberteil bzw. die Erreichung der gewünschten Eigenschaften problematisch.The DE 1 934 235 U discloses a similar dispensing device, wherein an elastically deformable upper part is approximately hemispherical and has to increase the restoring force on the outside radial stiffening ribs, which terminate in an annular bead on the head of the upper part. The annular bead also serves to guide a finger when depressing the upper part. Here too the right choice of material for the upper part or the achievement of the desired properties is problematic.

Die WO 01/34485 A1 offenbart eine Abgabevorrichtung mit einer elastisch verformbaren Pumpkammer, in die ein separater Einsatz zur elastischen Rückstellung der Pumpkammer eingesetzt ist. Hier ist die Herstellung durch den separaten Einsatz gegenüber dem vorgenannten Stand der Technik aufwendiger. Des weiteren besteht das Problem, daß ein für die zu pumpende Flüssigkeit ausreichend chemisch widerstandsfähiges Material sowohl für den Einsatz als auch für die Wandungen der Pumpkammer gefunden werden muß.The WO 01/34485 A1 discloses a dispenser having an elastically deformable pumping chamber into which a separate insert for resiliently returning the pumping chamber is inserted. Here, the production by the separate use over the aforementioned prior art is more complicated. Furthermore, there is the problem that a sufficiently chemically resistant material for the liquid to be pumped must be found both for use and for the walls of the pumping chamber.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine verbesserte Abgabevorrichtung anzugeben, die bei einfachem, kostengünstigem Aufbau insbesondere auch eine Ausgabe höher viskoser bzw. pastöser Flüssigkeiten bzw. Produkte und/oder eine Verbesserung der elastischen Eigenschaften, wie der Rückstellung, und/oder einen verbesserten Schutz eines insbesondere elastisch verformbaren Bauteils bzw. Materials, vorzugsweise gegen die Flüssigkeit, ermöglicht.The present invention has for its object to provide an improved dispensing device, which in a simple, inexpensive construction in particular also an output of higher viscous or pasty liquids or products and / or an improvement in the elastic properties, such as the provision, and / or improved Protection of a particular elastically deformable component or material, preferably against the liquid allows.

Die obige Aufgabe wird durch eine Abgabevorrichtung gemäß Anspruch 1 gelöst. Vorteilhafte Weiterbildungen sind Gegenstand der Unteransprüche.The above object is achieved by a dispensing device according to claim 1. Advantageous developments are the subject of the dependent claims.

Ein Aspekt der vorliegenden Erfindung liegt darin, eine Wandung oder einen sonstigen Abschnitt des Bauteils - vorzugsweise im Bereich eines Pumpraums und/oder eines sonstigen insbesondere bei der Benutzung elastisch verformbarer und/oder mit der Flüssigkeit in Kontakt kommenden Bereichs - mit einem Element aus einem zweiten Material zu verbinden. Dies gestattet bei einfachem Aufbau bzw. einfacher Montage der Abgabevorrichtung wesentlich größere konstruktive Freiheiten und größere Freiheiten bei der Materialwahl.One aspect of the present invention resides in a wall or another section of the component-preferably in the region of a pumping space and / or another region that is elastically deformable and / or in contact with the liquid, in use-with an element of a second Material to connect. This allows for a simple design and easy installation of the dispenser much greater design freedom and greater freedom in the choice of materials.

Das Element bzw. Material kann nämlich die elastischen bzw. Rückstelleigenschaften des Bauteils verbessern oder modifizieren und/oder gegen chemische oder sonstige Einwirkungen schützen.Namely, the element or material can improve or modify the elastic or restoring properties of the component and / or protect it against chemical or other influences.

Ein anderer, auch unabhängig realisierbarer Aspekt der Erfindung liegt in der Abdeckung der Wandung bzw. des ersten Materials durch das Element bzw. zweite Material, vorzugsweise auf der Seite der Flüssigkeit. Insbesondere bildet gemäß einer bevorzugten Ausführungsvariante das Element bzw. zweite Material eine durchgehende Materialschicht oder Abdeckung des Bauteils, der Wandung bzw. des ersten Materials, insbesondere zumindest im Bereich des Pumpraums und/oder eines sonstigen mit der Flüssigkeit in Kontakt kommenden Oberflächenbereichs. So kann das erste Material vor chemischen und/oder sonstigen Einwirkungen geschützt und/oder ein unerwünschter Kontakt der Flüssigkeit mit dem ersten Material vermieden werden. entsprechend können auch solche Materialien als erstes Material eingesetzt werden, die üblicherweise für die Flüssigkeit bzw. Kosmetika oder den Lebensmittelbereich nicht geeignet oder nicht zugelassen sind.Another aspect of the invention, which can also be implemented independently, is the covering of the wall or of the first material by the element or second material, preferably on the side of the liquid. In particular, forms According to a preferred embodiment variant, the element or second material comprises a continuous material layer or covering of the component, the wall or the first material, in particular at least in the area of the pumping space and / or another surface area coming into contact with the liquid. Thus, the first material can be protected from chemical and / or other influences and / or unwanted contact of the liquid with the first material can be avoided. Accordingly, such materials can be used as the first material that are usually not suitable or not approved for the liquid or cosmetics or the food industry.

Gemäß der Erfindung bedeckt das Element die aus dem ersten Material bestehende Wandung - zumindest im, Bereich des Pumpraums - nicht vollständig. Der Element weist rippen- oder stegartige, sich über die Wandung erstreckende Abschnitte auf. So kann insbesondere eine optimale bzw. gewünschte Rückstellung oder Elastizität des Bauteils erreicht werden.According to the invention, the element does not completely cover the wall made of the first material, at least in the region of the pumping space. The element has rib or web-like sections extending over the wall. In particular, an optimal or desired return or elasticity of the component can be achieved.

Das Element ist vorzugsweise unmittelbar an das Bauteil bzw. dessen Wandung angespritzt. Dies ermöglicht eine einfache Herstellung, beispielsweise durch sogenannte "Bi-Injection", also insbesondere Anspritzen in der gleichen Spritzform, in der die Wandung und ggf. weitere Bereiche des Bauteils hergestellt werden.The element is preferably molded directly onto the component or its wall. This allows a simple production, for example by so-called "bi-injection", ie in particular injection molding in the same injection mold, in which the wall and possibly other areas of the component are produced.

Fig. 1 zeigt eine erste Ausführungsform einer vorschlagsgemäßen Abgabevorrichtung 1 zur Abgabe einer vorzugsweise kosmetischen Flüssigkeit 2, im eingangs genannten Sinn. Die Flüssigkeit 2 kann wesentlich höher viskos sein als Wasser oder ggf. sogar pastös. Fig. 1 shows a first embodiment of a proposed dispensing device 1 for dispensing a preferably cosmetic liquid 2, in the sense mentioned. The liquid 2 can be much higher than water viskos or possibly even pasty.

Der Abgabevorrichtung 1 ist vorzugsweise ein Behälter 3 zur Versorgung mit der Flüssigkeit 2 zugeordnet, an dem die Abgabevorrichtung 1 bedarfsweise lösbar befestigt ist. So kann gegebenenfalls ein Austausch des Behälters 3 und/oder ein Nachfüllen der Flüssigkeit 2 erfolgen. Alternativ kann die Abgabevorrichtung 1 auch ein Reservoir für die Flüssigkeit 2 oder den Behälter bilden.The dispensing device 1 is preferably associated with a container 3 for supply with the liquid 2, to which the dispensing device 1 is releasably attached as needed. Thus, if necessary, an exchange of the container 3 and / or a refilling of the liquid 2 take place. Alternatively, the dispenser 1 may also form a reservoir for the liquid 2 or the container.

Die Abgabevorrichtung 1 weist ein Unterteil 4 und ein Bauteil 5, insbesondere ein Oberteil, auf. Die Bezeichnungen "Unterteil" und "Oberteil" entsprechen bei der Darstellung gemäß Fig. 1 der bevorzugten Anordnung bzw. Ausrichtung der Abgabevorrichtung 1 bei normaler Benutzung. Dies ist jedoch nicht zwingend der Fall. Dementsprechend können je nach Bedarf, Anwendung, Ausbildung u. dgl. das Unterteil 4 und das Bau- bzw. Oberteil 5 auch in beliebiger räumlicher Ausrichtung zueinander stehen bzw. ausgerichtet sein.The dispensing device 1 has a lower part 4 and a component 5, in particular an upper part. The terms "lower part" and "upper part" correspond to the illustration in accordance with Fig. 1 the preferred arrangement or orientation of the dispensing device 1 during normal use. However, this is not necessarily the case. Accordingly, depending on needs, application, training u. Like. The lower part 4 and the building or upper part 5 are also in any spatial orientation to each other or be aligned.

Das Unterteil 4 ist vorzugsweise starr und/oder einstückig ausgebildet, insbesondere aus einem geeigneten Kunststoff gespritzt.The lower part 4 is preferably rigid and / or integrally formed, in particular injection molded from a suitable plastic.

Das Bauteil 5 ist elastisch verformbar ausgebildet. Die vorschlagsgemäße Ausbildung des Bauteils 5 wird später näher erläutert.The component 5 is formed elastically deformable. The proposed design of the component 5 will be explained later.

Die Abgabevorrichtung 1 weist weiter einen Aufnahme- oder Pumpraum 6 für die Flüssigkeit 2 auf, der insbesondere ausschließlich vor bzw. zwischen dem Bauteil 5 und dem Unterteil 4 gebildet oder begrenzt ist.The dispensing device 1 further has a receiving or pumping chamber 6 for the liquid 2, which is in particular formed or limited exclusively before or between the component 5 and the lower part 4.

Vorzugsweise bildet das Bauteil 5 ggf. zusammen mit dem Unterteil 4 ein Einlaßventil 7 und/oder ein Auslaßventil 8. Jedoch können die Ventile 7, 8 auch separat gebildet sein. Aufgrund der Ventile 7, 8 wird vorzugsweise die Funktionalität einer Pumpe ermöglicht. Die Ventile 7, 8 sind vorzugsweise als selbst schließende Einwegventile ausgebildet.Preferably, the component 5 optionally together with the lower part 4 forms an inlet valve 7 and / or an outlet valve 8. However, the valves 7, 8 may also be formed separately. Due to the valves 7, 8, the functionality of a pump is preferably made possible. The valves 7, 8 are preferably designed as self-closing one-way valves.

Wenn der Pumpraum 6 mit Flüssigkeit 2 gefüllt ist, wie in Fig. 1 dargestellt, kann durch Verformen des Bauteils 5 das Volumen des Pumpraums 6 verkleinert und dadurch Flüssigkeit 2 aus dem Pumpraum 6 verdrängt und ausgegeben werden. Insbesondere wird hierzu ein optionales Betätigungselement 9 vorzugweise manuell in Richtung des Pfeils N und dadurch zumindest ein Betätigungsabschnitt 10 des Bauteils 5 niedergedrückt. Jedoch ist es beispielsweise auch möglich, daß ein nicht dargestellter Benutzer unmittelbar auf das Bauteil 5 bzw. den Betätigungsabschnitt 10 zur Ausgabe von Flüssigkeit 2 drückt.When the pumping space 6 is filled with liquid 2, as in FIG Fig. 1 represented, can be reduced by deforming the component 5, the volume of the pump chamber 6 and thereby liquid 2 displaced from the pump chamber 6 and output. In particular, for this purpose, an optional actuator 9 is preferably depressed manually in the direction of the arrow N and thereby at least one operating portion 10 of the component 5. However, it is also possible, for example, for an unillustrated user to press directly on the component 5 or the actuating portion 10 for dispensing liquid 2.

Die verdrängte Flüssigkeit 2 wird über das Auslaßventil 8 aus- bzw. abgegeben. Das Öffnen des Auslaßventils 8 erfolgt insbesondere selbsttätig, vorzugsweise aufgrund des Flüssigkeitsdrucks, und/oder - ggf. zusätzlich - aufgrund einer entsprechenden Verformung des Bauteils 5 beim Niederdrücken.The displaced liquid 2 is discharged via the outlet valve 8 and discharged. The opening of the outlet valve 8 takes place in particular automatically, preferably due to the fluid pressure, and / or - possibly additionally - due to a corresponding deformation of the component 5 during depression.

Aufgrund der Eigenelastizität bzw. der Rückstellkraft des Befestigungsabschnitts 10 bzw. des Bauteils 5 erfolgt dann nach dem Loslassen ein selbsttätiges Rückstellen gemäß Pfeil R in die in Fig. 1 gezeigte Ausgangslage, wobei neue Flüssigkeit 2 über das Einlaßventil 7 in den Pumpraum 6 aufgenommen, insbesondere eingesaugt, wird. Das Öffnen des Einlaßventils 7 während des Rückstellens erfolgt vorzugsweise aufgrund des dann im Pumpraum 6 herrschenden Unterdrucks. Die Elastizität bzw. Rückstellkraft des Bauteils 5 ist an die Viskosität und/oder die Strömungswiderstände angepaßt, um ein ausreichend schnelles und/oder sicheres Rückstellen und damit erneutes Füllen des Pumpraums 6 zu gewährleisten. Während des Rückstellens bzw. erneuten Füllens des Pumpraums 6 bleibt das Auslaßventil 8 geschlossen.Due to the inherent elasticity or the restoring force of the mounting portion 10 and the component 5 is then carried out after releasing an automatic reset according to arrow R in the in Fig. 1 shown starting position, wherein new liquid 2 received via the inlet valve 7 into the pump chamber 6, in particular sucked, is. The opening of the inlet valve 7 during the reset is preferably carried out due to the then prevailing in the pump chamber 6 negative pressure. The elasticity or restoring force of the component 5 is adapted to the viscosity and / or the flow resistance in order to ensure a sufficiently fast and / or safe resetting and thus refilling the pump chamber 6. During the return or refilling of the pump chamber 6, the exhaust valve 8 remains closed.

Das Bauteil 5 weist vorzugsweise einen zumindest im wesentlichen umlaufenden Ringabschnitt 11 auf, der insbesondere das Einlaßventil 7 und/oder das Auslaßventil 8 bildet.The component 5 preferably has an at least substantially circumferential annular portion 11 which forms in particular the inlet valve 7 and / or the outlet valve 8.

Der Ringabschnitt 11 ist vorzugsweise zumindest im wesentlichen über seine gesamte periphere Erstreckung vom Unterteil 4 radial von außen und/oder innen abgestützt. Der Ringabschnitt 11 ist jedoch zumindest bereichsweise radial nach innen elastisch auslenkbar, nämlich zumindest im Bereich einer vorzugsweise im Unterteil 4 gebildeten Einlaßöffnung 12. Im nicht ausgelenkten Zustand überdeckt und schließt der Ringabschnitt 9 die Einlaßöffnung 12. Beim Rückstellen des Bauteils 5 bzw. Ansaugen von Flüssigkeit 2 wird der Ringabschnitt 11 aufgrund des in der Einlaßöffnung 12 entstehenden Flüssigkeitsdrucks ausgelenkt und dadurch die Einlaßöffnung 12 für die Flüssigkeit 2 freigegeben. Der Ringabschnitt 11 bildet also zusammen mit dem Unterteil 4 bzw. der Einlaßöffnung 12 beim Darstellungsbeispiel das Einlaßventil 7.The ring portion 11 is preferably at least substantially over its entire peripheral extent of the lower part 4 radially supported from the outside and / or inside. However, the annular portion 11 is elastically deflectable at least in regions radially inwardly, namely at least in the region of an inlet opening 12 formed preferably in the lower part 4. In undeflected state covers and closes the ring section 9, the inlet opening 12. When resetting the component 5 or suction of liquid 2, the annular portion 11 is deflected due to the liquid pressure arising in the inlet opening 12, thereby releasing the inlet opening 12 for the liquid 2. The annular portion 11 thus forms, together with the lower part 4 and the inlet opening 12 in the illustrated example, the inlet valve. 7

Der Ringabschnitt 11 ist vorzugsweise zumindest im wesentlichen hohlzylindrisch ausgebildet. Vorzugsweise ist die Ringwandung zu ihrem freien axialen Ende hin in ihrer radialen Dicke verringert bzw. verjüngt.The ring portion 11 is preferably formed at least substantially hollow cylindrical. Preferably, the annular wall is reduced or tapered towards its free axial end in its radial thickness.

Alternativ oder zusätzlich kann der Ringabschnitt 9 jedoch auch mit einer Durchbrechung, einer Ausnehmung, einem axialen Schlitz od. dgl. versehen sein, um einen gewünschten Durchlaß zu bilden und/oder eine gewünschte, insbesondere radiale Auslenkung bzw. Verformung zu ermöglichen.Alternatively or additionally, however, the annular portion 9 can also be provided with an opening, a recess, an axial slot or the like in order to form a desired passage and / or to permit a desired, in particular radial, deflection or deformation.

Zur Zuleitung der Flüssigkeit 2 weist die Abgabevorrichtung 1 beim Darstellungsbeispiel vorzugsweise einen Anschlußstutzen 13 mit einem daran angeschlossenen, sich in den Behälter 2 erstreckenden Saugschlauch 14 od. dgl. auf. Vorzugsweise ist der Anschlußstutzen 13 an das Unterteil 4 angeformt.To supply the liquid 2, the dispensing device 1 in the illustrated embodiment, preferably a connecting piece 13 with a connected thereto, extending into the container 2 suction hose 14 od. Like. On. Preferably, the connecting piece 13 is integrally formed on the lower part 4.

Das Auslaßventil 8 ist vorzugsweise bezüglich der Achse des Ringabschnitts 11 diametral gegenüberliegend zum Einlaßventil 7 angeordnet. Im Bereich des Auslaßventils 8 ist der Ringabschnitt 11 radial innen abgestützt, vorzugsweise von einem Wandabschnitt 15 des Unterteils 4. Besonders bevorzugt ist der Wandabschnitt 15 durch eine innere Erhebung des Unterteils 4 in den Pumpraum 6 gebildet.The outlet valve 8 is preferably arranged diametrically opposite the intake valve 7 with respect to the axis of the annular portion 11. In the region of the outlet valve 8, the ring portion 11 is supported radially inwardly, preferably by a wall portion 15 of the lower part 4. Particularly preferred is the wall portion 15 formed by an inner elevation of the lower part 4 in the pump chamber 6.

Zur Bildung des Auslaßventils 8 überdeckt der Ringabschnitt 11 eine im Wandabschnitt 15 gebildete Auslaßöffnung 16 radial außenseitig. Insbesondere ist der Ringabschnitt 11 elastisch gegen die Auslaßöffnung 16 - also radial nach innen - vorgespannt oder überdeckt die Auslaßöffnung 16 zumindest lose.To form the outlet valve 8, the ring section 11 covers an outlet opening 16 formed in the wall section 15 radially on the outside. In particular, the ring portion 11 is elastically biased against the outlet opening 16 - ie radially inwardly - or covers the outlet opening 16 at least loosely.

Bei Betätigung bzw. Niederdrücken des Bauteils 5 bzw. Betätigungsabschnitts 10, insbesondere in Niederdrückrichtung N, wird im Pumpraum 6 befindliche Flüssigkeit 2 unter Druck gesetzt, so daß diese den Ringabschnitt 11 im Bereich der Auslaßöffnung 16 radial nach außen auslenkt, wodurch das Auslaßventil 8 geöffnet wird und die Ausgabe der Flüssigkeit 2, insbesondere über einen sich anschließenden, beispielsweise rüsselartigen Abgabekanal 17, erfolgen kann.Upon actuation or depression of the component 5 or actuation section 10, in particular in the depression direction N, liquid 2 located in the pump chamber 6 is pressurized so that it deflects the annular section 11 radially outward in the region of the outlet opening 16, whereby the outlet valve 8 is opened is and the output of the liquid 2, in particular via a subsequent, for example, trunk-like discharge channel 17, can take place.

Anschließend schließt das Auslaßventil 8 - insbesondere aufgrund der Eigenelastizität bzw. Rückstellkraft des Ringabschnitts 11 - wieder zumindest im wesentlichen vollständig.Subsequently, the exhaust valve 8 closes again - at least substantially completely, in particular due to the inherent elasticity or restoring force of the annular section 11.

Beim Darstellungsbeispiel öffnen und schließen die Ventile 7, 8 zumindest im wesentlichen durch axiale Bewegung bzw. Auslenkung oder Verformung des Ringabschnitts 11 und/oder zumindest im wesentlichen senkrecht zur Hauptbetätigungsrichtung bzw. Niederdrückrichtung N des Bauteils 5 bzw. des Betätigungsabschnitts 10. Jedoch sind auch andere Anordnungen möglich.In the illustrated example, the valves 7, 8 open and close at least substantially by axial movement or deflection or deformation of the ring section 11 and / or at least substantially perpendicular to the main operating direction or depression direction N of the component 5 or of the actuating section 10, however Arrangements possible.

Die Ausgabe von Flüssigkeit 2 durch die Abgabevorrichtung 1 erfolgt insbesondere in nicht zerstäubtem Zustand. Grundsätzlich ist jedoch auch eine Zerstäubung der Flüssigkeit 2 mittels der Abgabevorrichtung 1 möglich.The dispensing of liquid 2 by the dispensing device 1 takes place in particular in a non-atomized state. In principle, however, a sputtering of the liquid 2 by means of the dispensing device 1 is possible.

Die Abgabevorrichtung 1 weist vorzugsweise ein Verbindungsteil 18 zur Halterung des Bauteils 5 und insbesondere Verbindung des Bauteils 5 mit dem Unterteil 4 auf. Insbesondere ist das Verbindungsteil 18 im wesentlichen hülsenförmig und/oder starr - zumindest im Vergleich zum Bauteil 5 - ausgebildet. Besonders bevorzugt ist das Verbindungsteil 18 direkt an das Bauteil 5 angespritzt, insbesondere durch sogenannte "Bi-Injection", also Spritzen eines anderen Materials gegen ein erstes Material. Besonders bevorzugt ist das Bauteil 5 peripher umlaufend am Verbindungsteil 18 gelagert bzw. gehalten.The dispensing device 1 preferably has a connecting part 18 for holding the component 5 and in particular connection of the component 5 with the lower part 4. In particular, the connecting part 18 is substantially sleeve-shaped and / or rigid - at least in comparison to the component 5 - formed. Particularly preferably, the connecting part 18 is molded directly onto the component 5, in particular by so-called "bi-injection", ie spraying of another material against a first material. Particularly preferably, the component 5 is mounted peripherally peripherally on the connecting part 18 and held.

Das Unterteil 4 ist vorzugsweise in das Verbindungsteil 18 eingesetzt, beispielsweise eingeklebt, eingeklemmt oder eingerastet.The lower part 4 is preferably inserted into the connecting part 18, for example glued, clamped or engaged.

Jedoch ist es auch möglich, daß das Bauteil 5 nur direkt mit dem Unterteil 4 verbunden oder vorzugsweise zumindest im wesentlichen selbstdichtend und/oder selbsthaltend am Unterteil 4 gehalten ist. Bedarfsweise zusätzlich können zur Verbindung auch hinterschnittene Abschnitte, Rastungen oder dergleichen ineinandergreifen.However, it is also possible that the component 5 is connected only directly to the lower part 4 or is preferably held at least substantially self-sealing and / or self-holding on the lower part 4. If necessary, in addition can intermesh for connection and undercut sections, detents or the like.

Bisher war das Bauteil 5 einstückig aus einem einzigen Material hergestellt. Vorschlagsgemäß ist das Bauteil 5 jedoch modifiziert, wie insbesondere nachfolgend erläutert und/oder in den Ansprüchen offenbart.So far, the component 5 was made in one piece from a single material. However, according to the proposal, the component 5 is modified, as explained in particular below and / or disclosed in the claims.

Beim Darstellungsbeispiel bildet das Bauteil 5 eine vorzugsweise durchgehende, insbesondere gewölbte Wandung 19 zumindest im Bereich des Pumpraums 6. Die Wandung 19 bildet insbesondere den primär verformbaren Bereich, insbesondere Betätigungsabschnitt 10, des Bauteils 5. Beim Darstellungsbeispiel ist das Bauteil 5 bzw. die Wandung 19 vorzugsweise kuppel- bzw. kalottenförmig, insbesondere halbkugelförmig, ausgebildet. Jedoch sind auch andere Formen und/oder andere Einsatzzwecke des Bauteils 5, beispielsweise für Behälterwandungen, Ventilteile, Federabschnitte oder dergleichen - je nach Anwendungsfall - möglich.In the illustrated embodiment, the component 5 forms a preferably continuous, in particular curved wall 19 at least in the region of the pump chamber 6. The wall 19 forms in particular the primary deformable region, in particular actuating portion 10, of the component 5. In the illustration example, the component 5 or the wall 19 preferably dome-shaped or dome-shaped, in particular hemispherical, formed. However, other shapes and / or other purposes of the component 5, for example, for container walls, valve parts, spring sections or the like - depending on the application - possible.

Die Wandung 19 besteht aus einem ersten Material. Vorzugsweise besteht das Bauteil 5 zumindest im wesentlichen aus diesem ersten Material, insbesondere auch dessen sonstige Abschnitte bzw. Bereiche, wie beim Darstellungsbeispiel der Ringabschnitt 11, alternativ oder zusätzlich aber auch sonstige vorzugsweise einstückig angeformte Abschnitte, wie Ventillappen, Abstützungen, Halteabschnitte, Flanschabschnitte, Verstärkungen, od. dgl.The wall 19 is made of a first material. Preferably, the component 5 at least substantially consists of this first material, in particular its other sections or areas, as in the illustrated embodiment of the ring section 11, alternatively or additionally but also other preferably integrally molded sections, such as valve flaps, supports, holding sections, flange sections, reinforcements , od. Like.

Vorschlagsgemäß ist das Bauteil 5 insbesondere zumindest im Bereich des Pumpraums 6 bzw. der Wandung 19 mit einem Element 20 aus einem zweiten Material versehen. Bei der ersten Ausführungsform gemäß Fig. 1 ist das Element 20 in das Bauteil 5 bzw. die Wandung 19 integriert, insbesondere in das erste Material eingespritzt bzw. von diesem umspritzt.According to the proposal, the component 5 is provided in particular at least in the region of the pumping space 6 or the wall 19 with an element 20 made of a second material. In the first embodiment according to Fig. 1 is the element Integrated into the component 5 and the wall 19, in particular injected into the first material or encapsulated by this.

Das Element 20 ist hier beispielsweise flächig, faserartig oder gitterartig ausgebildet. Vorzugsweise ist das Element 20 auch durch Spritzgießen oder in sonstiger geeigneter Weise hergestellt.The element 20 is formed here, for example, flat, fibrous or lattice-like. Preferably, the element 20 is also made by injection molding or other suitable means.

Das Bauteil 5 ist vorzugsweise spritzgegossen. Das erste Material ist vorzugsweise ein Kunststoff, insbesondere ein Elastomer und/oder Thermoplast. Jedoch kann es sich grundsätzlich auch um ein sonstiges Material handeln. Dies gilt insbesondere, wenn das Bauteil 5 nicht (nur) die Wandung 19 für den Pumpraum 6 oder ein sonstiges Pumpenteil, sondern eine andere Komponente der Abgabevorrichtung 1 bildet.The component 5 is preferably injection-molded. The first material is preferably a plastic, in particular an elastomer and / or thermoplastic. However, it can basically also be a different material. This is especially true if the component 5 is not (only) the wall 19 for the pump chamber 6 or another pump part, but another component of the dispensing device 1 forms.

Das erste Material ist vorzugsweise ein Elastomer, Gummi oder sonstiger Thermoplast. Bevorzugt wird TBE (thermoplastisches Elastomer), TPV, TEEE (thermoplastische Elastomere mit Ether- und Ester-Gruppen) oder TPO (thermoplastische Urethane) eingesetzt.The first material is preferably an elastomer, rubber or other thermoplastic. Preference is given to using TBE (thermoplastic elastomer), TPV, TEEE (thermoplastic elastomers with ether and ester groups) or TPO (thermoplastic urethanes).

Vorzugsweise handelt es sich bei dem zweiten Material ebenfalls um ein Elastomer und/oder einen Thermoplasten, bedarfsweise aber auch um ein sonstiges Material.Preferably, the second material is also an elastomer and / or a thermoplastic, but if necessary also another material.

Besonders bevorzugt handelt es sich bei dem zweiten Material um ein Polyolefin, insbesondere PP (Polypropylen) oder PE (Polyethylen).Particularly preferably, the second material is a polyolefin, in particular PP (polypropylene) or PE (polyethylene).

Es ist anzumerken, daß das erste Material und das zweite Material verschieden sind, also zumindest unterschiedliche Eigenschaften und/oder zumindest unterschiedliche Zusammensetzungen aufweisen. Durch die Kombination verschiedener Materialien lassen sich wesentlich einfacher die gewünschten Eigenschaften des Bauteils 5, beispielsweise im Bereich der Wandung 19 bzw. in dem für das Pumpen elastisch verformbaren Bereich, erreichen.It should be noted that the first material and the second material are different, ie have at least different properties and / or at least different compositions. The combination of different materials makes it much easier to achieve the desired properties of the component 5, for example in the region of the wall 19 or in the region which is elastically deformable for the pumping.

Bei der ersten Ausführungsform gemäß Fig. 1 dient das Element 20 insbesondere einer Optimierung der elastischen Eigenschaften des Bauteils 5 bzw. der Wandung 19, insbesondere der elastischen Rückstellung. Aufgrund der Integration in das erste Material bzw. die Wandung 19 kommt das zweite Material nicht mit der Flüssigkeit 2 in Kontakt. Dementsprechend kann ein für die elastischen Eigenschaften optimales Material unabhänigig von seiner chemischen Beständigkeit gegenüber der Flüssigkeit 2 eingesetzt werden.In the first embodiment according to Fig. 1 In particular, the element 20 serves to optimize the elastic properties of the component 5 or the wall 19, in particular the elastic return. Due to the integration in the first material or the wall 19, the second material does not come into contact with the liquid 2. Accordingly, an optimum material for the elastic properties can be used regardless of its chemical resistance to the liquid 2.

Das Element 20 ist mit dem Bauteil 5 bzw. dessen Wandung 19 unlösbar verbunden. Alternativ zum Einspritzen kann das das Element 20 auch selbst angespritzt oder umgekehrt die Wandung 19 gegen das Element 20 gespritzt werden, besonders bevorzugt durch die bereits genannte "Bi-Injection". Alternativ kann das Element 20 grundsätzlich auch durch Kleben, Schweißen oder in sonstiger geeigneter Weise mit dem Bauteil 5 bzw. der Wandung 19 verbunden sein.The element 20 is permanently connected to the component 5 or its wall 19. As an alternative to injecting, the element 20 may also be injection-molded on its own or, conversely, the wall 19 may be sprayed against the element 20, particularly preferably by the "bi-injection" already mentioned. Alternatively, the element 20 can in principle also be connected to the component 5 or the wall 19 by gluing, welding or in any other suitable manner.

Nachfolgend wird eine zweite Ausführungsform der vorschlagsgemäßen Abgabevorrichtung 1 anhand von Fig. 2 erläutert, die einen schematischen Schnitt entsprechend Fig. 1 zeigt. Es werden lediglich wesentliche Unterschiede gegenüber der ersten Ausführungsform hervorgehoben. Die bisherigen Ausführungen und Erläuterungen gelten also entsprechend oder zumindest ergänzend.Hereinafter, a second embodiment of the proposed dispensing device 1 based on Fig. 2 explained, which corresponds to a schematic section Fig. 1 shows. Only essential differences from the first embodiment are highlighted. The previous statements and explanations therefore apply accordingly or at least supplementary.

Bei der zweiten Ausführungsform ist das erste Material des Bauteils 5 vorzugsweise vollständig in dem Bereich, der mit der Flüssigkeit 2 in Kontakt steht oder kommt, durch das zweite Material abgedeckt. Insbesondere bildet das Element 20 also eine durchgehende Abdeckung bzw. Schicht oder Beschichtung aus dem zweiten Material. Das zweite Material bzw. die Schicht ist vorzugsweise fest, unlösbar und/oder vollflächig mit dem ersten Material verbunden. Hierzu kann das zweite Material insbesondere durch die sogenannte "Bi-Injection" an das erste Material angespritzt sein, wobei das erste Material teilweise eine zumindest im wesentlichen glatte oder rauhe Oberfläche oder eine mit Hinterschneidungen, Ausnehmungen, Durchbrechungen oder dergleichen versehene Oberfläche aufweisen bzw. bilden kann. Alternativ kann das Element 20 bzw. die Materialschicht auch nur bereichsweise, mit dem ersten Mal verbunden oder zusammen mit diesem - beispielsweise in Rand- oder Umfangsbereichen - gehalten sein. Alternativ wurde zusätzlich zu einer chemischen Verbindungen der beiden Materialien ist also auch eine mechanische, insbesondere kraft- oder formflüssige Verbindung möglich. Alternativ kann das Element 20 auch nur ein insbesondere membranartiges Teil bilden, das zwischen Flüssigkeit 2 und Bauteil 5 eingesetzt bzw. angeordnet ist. Gemäß einer nicht dargestellten Alternative kann das zweite Material auch eine Hülle bilden, die das erste Material vorzugsweise vollständig umgibt. Auch in diesem Fall ist eine unmittelbare Verbindung der beiden Materialien nicht erforderlich.In the second embodiment, the first material of the component 5 is preferably completely covered by the second material in the region which is in contact or comes into contact with the liquid 2. In particular, the element 20 thus forms a continuous cover or layer or coating of the second material. The second material or the layer is preferably fixed, insoluble and / or full surface connected to the first material. For this purpose, the second material may in particular be molded onto the first material by the so-called "bi-injection", the first material partially having or forming an at least substantially smooth or rough surface or a surface provided with undercuts, recesses, perforations or the like can. Alternatively, the element 20 or the material layer may also be connected only in regions, for the first time, or held together with the latter - for example in edge or peripheral areas. Alternatively, in addition to a chemical compounds of the two materials, therefore, a mechanical, in particular force or form liquid connection is possible. Alternatively, the element 20 may also form only a particular membrane-like part which is inserted or arranged between liquid 2 and component 5. According to an alternative, not shown, the second Material also form a shell, which preferably completely surrounds the first material. Also in this case, a direct connection of the two materials is not required.

Die flüssigkeitsseitige bzw. innenseitige Anordnung des zweiten Materials bzw. Abdeckung des ersten Materials schützt das erste Material gegen chemische Einflüsse, insbesondere durch die Flüssigkeit 2 und/oder die Flüssigkeit 2 vor chemischen Einflüssen des ersten Materials oder sonstigen Wechselwirkungen. So ist es beispielsweise möglich, nicht lebensmittelechte Materialien und/oder nicht gegenüber der Flüssigkeit 2 resistente Materialien als erstes Material einzusetzen, um beispielsweise eine kostengünstige Herstellung und/oder bestimmte mechanische oder sonstige Eigenschaften zu erreichen. Das zweite Material kann dann die gewünschte Lebensmittelechtheit bzw. Resistenz gegenüber der Flüssigkeit 2 erfüllen.The liquid-side or inside arrangement of the second material or cover of the first material protects the first material against chemical influences, in particular by the liquid 2 and / or the liquid 2 from chemical influences of the first material or other interactions. It is thus possible, for example, to use non-food-grade materials and / or non-liquid-resistant materials as the first material in order, for example, to achieve cost-effective production and / or certain mechanical or other properties. The second material can then fulfill the desired food-fastness or resistance to the liquid 2.

Beim Darstellungsbeispiel überdeckt das Element 20 bzw. das zweite Material die dem Pumpraum 6 zugewandte Oberfläche der Wandung 19, die Innenseite, Außenseite und die Stirnfläche des sich anschließenden Ringabschnitts 11 sowie des sich radial anschließenden Ringbereich des Ringflunsch 24 des Bauteils 5. Insbesondere erstreckt sich das zweite Material bzw. die davon gebildete Schicht oder Abdeckung bis zu oder sogar unter ein sonstiges, gegenüber der Flüssigkeit 2 resistentes bzw. inertes Material oder Bauteil, beim Darstellungsbeispiel das Unterteil 4 oder das Verbindungsteil 18.In the illustrated example, the element 20 or the second material covers the pump chamber 6 facing surface of the wall 19, the inside, outside and the end face of the adjoining ring portion 11 and the radially adjacent annular region of the annular die 24 of the component 5. In particular, this extends second material or the layer or cover formed therefrom up to or even below another material or component that is resistant or inert to the liquid 2, in the illustrated example the lower part 4 or the connecting part 18.

Zusätzlich zu der Abschirmung des ersten Materials kann das zweite Material bzw. Element 20 auch einer Modifizierung der elastischen Eigenschaften oder sonstigen Eigenschaften des Bauteils 5 dienen.In addition to the shielding of the first material, the second material or element 20 can also serve to modify the elastic properties or other properties of the component 5.

Es ist anzumerken, daß bei der vorliegenden Erfindung unter elastischen Eigenschaften und Rückstellung insbesondere auch generell die Verformbarkeit des Bauteils 5 als eine wesentliche bzw. damit zusammenhängende Eigenschaft zu verstehen ist.It should be noted that in the present invention elastic properties and resiliency in particular also generally the deformability of the component 5 is to be understood as a significant or related property.

Die vorliegende Erfindung ist jedoch nicht auf elastische bzw. flexible, insbesondere also verformbare Bauteile beschränkt. Vielmehr kann die Abdeckung durch das zweite Material generell auch bei jeder Art von Bauteil einer Abgabevorrichtung 1 im Sinne der vorliegenden Erfindung eingesetzt werden, insbesondere um einen unmittelbaren Kontakt zwischen Flüssigkeit 2 und Material zu verhindern.However, the present invention is not limited to elastic or flexible, in particular so deformable components. Rather, the cover by the second material generally also in any type of component of a dispenser 1 are used in the context of the present invention, in particular to prevent direct contact between liquid 2 and material.

Nachfolgend werden weitere Ausführungsformen des vorschlagsgemäß modifizierten Bauteils 5 anhand der Fig. 3 bis 5 erläutert, wobei jedoch lediglich wesentliche Unterschiede hervorgehoben werden. Die bisherigen Ausführungen und Erläuterungen gelten also entsprechend oder zumindest ergänzend.
Bei der dritten Ausführungsform gemäß Fig. 3 ist das Element 20 auf der dem Pumpraum 6 abgewandten Seite des Bauteils 5 bzw. der Wandung 19 - also Außenseite - angeordnet. Das Element 20 ist hier insbesondere als durchgehende Materialschicht bzw. Abdeckung ausgebildet. Vorzugsweise ist das Element 20 unmittelbar auf das erste Material gespritzt, insbesondere durch die genannte "Bi-Injection" od. dgl. Das Element 20 dient hier insbesondere wiederum einer Optimierung der Rückstelleigenschaften, insbesondere um eine ausreichend hohe Rückstellkraft erreichen zu können. Alternativ oder zusätzlich kann das Element 20 das Bauteil 5, insbesondere die Wandung 19 bzw. den Betätigungsabschnitt 10, gegen mechanische oder sonstige Einflüsse schützen.Hereinafter, further embodiments of the proposal according to modified component 5 based on Fig. 3 to 5 but highlights only significant differences. The previous statements and explanations therefore apply accordingly or at least supplementary.
In the third embodiment according to Fig. 3 is the element 20 on the pump chamber 6 facing away from the side of the component 5 and the wall 19 - that is outside - arranged. The element 20 is designed here in particular as a continuous material layer or cover. Preferably, the element 20 is sprayed directly onto the first material, in particular by the said "bi-injection" or the like. The element 20 serves in this case again in particular to optimize the return properties, in particular in order to be able to achieve a sufficiently high restoring force. Alternatively or additionally, the element 20 may protect the component 5, in particular the wall 19 or the actuating portion 10, against mechanical or other influences.

Alternativ oder zusätzlich kann die von dem Element 20 gebildete Abdeckung auch ein Entweichen von Weichmachern aus dem ersten Material verhindern, um so gewünschte Materialeigenschaften des ersten Materials gewährleisten zu können.Alternatively or additionally, the cover formed by the element 20 can also prevent the escape of plasticizers from the first material so as to be able to ensure desired material properties of the first material.

Gemäß einer nicht dargestellten Ausführungsvariante kann das Element 20 zusätzlich auf der dem Pumpraum 6 zugewandten Seite - also Innenseite - des Bauteils 5 bzw. der Wandung 19 angeordnet sein. In diesem Fall kann das Element 20 alternativ oder zusätzlich zu den vorgenannten Eigenschaften bzw. Wirkungen das erste Material gegen chemische Einflüsse - insbesondere durch die Flüssigkeit 2 - schützen. So ist es beispielsweise möglich, das erste Material hinsichtlich seiner elastischen Eigenschaften bzw. Rückstelleigenschaften zu optimieren oder optimal auszuwählen, unabhängig von seiner chemischen Widerstandskraft oder sonstigen Eigenschaften.According to an embodiment variant, not shown, the element 20 may additionally be arranged on the side facing the pumping space 6-that is, inside-of the component 5 or the wall 19. In this case, as an alternative or in addition to the aforementioned properties or effects, the element 20 may protect the first material against chemical influences, in particular by the liquid 2. Thus, it is possible, for example, to optimize or optimally select the first material with regard to its elastic properties or restoring properties, regardless of its chemical resistance or other properties.

Vorzugsweise ist das mit dem Pumpraum 6 bzw. der Flüssigkeit 2 in Kontakt stehende oder kommende Material - also das erste und/oder zweite Material - lebensmittelecht und/oder zumindest in ausreichendem Maße chemisch beständig.Preferably, the material that is in contact or coming into contact with the pumping space 6 or the liquid 2 is the first and / or second material. food safe and / or at least sufficiently chemically resistant.

Das Element 20 ist mit der Wandung 19 vorzugsweise vollflächig verbunden. Jedoch ist es grundsätzlich auch möglich, daß das Element 20 nur bereichsweise mit der Wandung 19 verbunden ist, beispielsweise nur entlang von Verschweißungslinien.The element 20 is preferably connected to the wall 19 over its entire surface. However, it is also possible in principle that the element 20 is only partially connected to the wall 19, for example only along welding lines.

Fig. 4 zeigt eine vierte Ausführungsform des vorschlagsgemäßen Bauteils 5. Das Element 20 ist hier auf der Außenseite der Wandung 19 angeordnet. Das Element 20 überdeckt die Wandung 19 nicht vollständig, ist also nicht durchgehend ausgebildet, sondern insbesondere mit Durchbrechungen oder Öffnungen versehen. Beim Darstellungsbeispiel weist das Element 20 insbesondere rippen- bzw. stegartige Abschnitte 21 auf, die einen inneren Ring 22 mit einem äußeren Ring 23 des Elements 20 - vorzugsweise radial und/oder mit gebogenem Verlauf - verbinden. Durch entsprechende Anpassung, beispielsweise von Anzahl, Querschnitt, Breite, Höhe, Verlauf der Abschnitte 21, die Dimensionierung des inneren Rings 22 und/oder des äußeren Rings 23, Auswahl eines entsprechenden Materials u. dgl., ist das gewünschte Rückstellverhalten sehr einfach realisierbar. Fig. 4 shows a fourth embodiment of the proposed component 5. The element 20 is arranged here on the outside of the wall 19. The element 20 does not cover the wall 19 completely, so it is not formed continuously, but in particular provided with openings or openings. In the illustrated example, the element 20 in particular rib-like or web-like portions 21 which connect an inner ring 22 with an outer ring 23 of the element 20 - preferably radially and / or with a curved course. By appropriate adaptation, for example of number, cross-section, width, height, course of the sections 21, the dimensioning of the inner ring 22 and / or the outer ring 23, selection of a corresponding material u. Like., The desired recovery behavior is very easy to implement.

Der äußere Ring 23 ist vorzugsweise axialseitig bzw. vollflächig mit einem Ringflansch 24 des Bauteils 5 verbunden, der sich radial an die Wandung 19 anschließt.The outer ring 23 is preferably connected on the axial side or the entire surface with an annular flange 24 of the component 5, which connects radially to the wall 19.

Zusätzlich kann der Ring 22 oder ein sonstiger, ggf. verstärkter oder vom Element 20 überdeckter Bereich der Wandung 19 den Betätigungsabschnitt 10 bzw. ein Widerlager oder Auflager für das Betätigungselement 9 bilden.In addition, the ring 22 or another region of the wall 19, possibly reinforced or covered by the element 20, can form the actuating section 10 or an abutment or support for the actuating element 9.

Fig. 5 zeigt eine fünfte Ausführungsform des vorschlagsgemäßen Bauteils 5 von unten. Hier ist das Element 20 auf der dem Pumpraum 6 zugewandten Seite - also Innenseite - angeordnet und vorzugsweise entsprechend der dritten Ausführungsform ausgebildet. Fig. 5 shows a fifth embodiment of the proposed component 5 from below. Here, the element 20 on the pump chamber 6 side facing - ie inside - arranged and preferably formed according to the third embodiment.

Einzelne Merkmale und konstruktive Lösungen der erläuterten Ausführungsformen und der genannten Ausführungsvarianten können auch beliebig miteinander kombiniert und/oder bei sonstigen Abgabevorrichtungen eingesetzt werden.Individual features and constructive solutions of the illustrated embodiments and the variants mentioned can also be combined with each other arbitrarily and / or used in other dispensing devices.
